The "Roma VF" variant is most common in seed catalogs as of 2007. It was developed by Agricultural Research Service (ARS) scientists in Beltsville, Maryland in the 1950s as a fusarium wilt-resistant cultivar.
While Roma is an open-pollinated variety rather than a hybrid, it has been steadily improved to the point where most Roma tomato vines are fusarium wilt and verticillium-resistant (thus the VF in the name).
Most commercial plum tomatoes sold in markets in the Western Hemisphere are Romas or related types. Smaller plum tomatoes about the size of cherry tomatoes are sometimes sold as "baby Romas". A smaller relative known as "Windowbox Roma" is sold as a tomato suitable for window gardens and hanging containers.
Roma tomatoes are egg or pear-shaped and generally available in red and yellow. It has few seeds and is a good canning and sauce tomato. While Roma is an open-pollinated variety, in general it is not considered an heirloom tomato. Maturing in under three months, the plant itself grows to 1.2 meters (4 feet) in height and the single fruit weighs about 110 grams (4 oz). The vines are purple and fruit heavily, making Roma a popular variety with gardeners who do a lot of home canning.
